[CRYPTO] api: Add aead crypto type This patch adds crypto_aead which is the interface for AEAD (Authenticated Encryption with Associated Data) algorithms. AEAD algorithms perform authentication and encryption in one step. Traditionally users (such as IPsec) would use two different crypto algorithms to perform these. With AEAD this comes down to one algorithm and one operation. Of course if traditional algorithms were used we'd still be doing two operations underneath. However, real AEAD algorithms may allow the underlying operations to be optimised as well. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: aead - Add new interface with single SG list The primary user of AEAD, IPsec includes the IV in the AD in most cases, except where it is implicitly authenticated by the underlying algorithm. The way it is currently implemented is a hack because we pass the data in piecemeal and the underlying algorithms try to stitch them back up into one piece. This is why this patch is adding a new interface that allows a single SG list to be passed in that contains everything so the algorithm implementors do not have to stitch. The new interface accepts a single source SG list and a single destination SG list. Both must be laid out as follows: AD, skipped data, plain/cipher text, ICV The ICV is not present from the source during encryption and from the destination during decryption. For the top-level IPsec AEAD algorithm the plain/cipher text will contain the generated (or received) IV. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] aead: Make authsize a run-time parameter As it is authsize is an algorithm paramter which cannot be changed at run-time. This is inconvenient because hardware that implements such algorithms would have to register each authsize that they support separately. Since authsize is a property common to all AEAD algorithms, we can add a function setauthsize that sets it at run-time, just like setkey.

[CRYPTO] aead: Allow algorithms with no givcrypt support Some algorithms always require manual IV construction.

[CRYPTO] aead: Add givcrypt operations This patch adds the underlying givcrypt operations for aead and associated support elements. The rationale is identical to that of the skcipher givcrypt operations, i.e., sometimes only the algorithm knows how the IV should be generated. A new request type aead_givcrypt_request is added which contains an embedded aead_request structure with two new elements to support this operation. The new elements are seq and giv. The seq field should contain a strictly increasing 64-bit integer which may be used by certain IV generators as an input value. The giv field will be used to store the generated IV. It does not need to obey the alignment requirements of the algorithm because it's not used during the operation. The existing iv field must still be available as it will be used to store intermediate IVs and the output IV if chaining is desired. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

IV generation will still be carried out by wrappers but they will be normal AEAD algorithms that simply take the IPsec sequence number as the IV.

crypto: aead - Add new interface with single SG list The primary user of AEAD, IPsec includes the IV in the AD in most cases, except where it is implicitly authenticated by the underlying algorithm. The way it is currently implemented is a hack because we pass the data in piecemeal and the underlying algorithms try to stitch them back up into one piece. This is why this patch is adding a new interface that allows a single SG list to be passed in that contains everything so the algorithm implementors do not have to stitch. The new interface accepts a single source SG list and a single destination SG list. Both must be laid out as follows: AD, skipped data, plain/cipher text, ICV The ICV is not present from the source during encryption and from the destination during decryption. For the top-level IPsec AEAD algorithm the plain/cipher text will contain the generated (or received) IV. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] aead: Make authsize a run-time parameter As it is authsize is an algorithm paramter which cannot be changed at run-time. This is inconvenient because hardware that implements such algorithms would have to register each authsize that they support separately. Since authsize is a property common to all AEAD algorithms, we can add a function setauthsize that sets it at run-time, just like setkey. This patch does exactly that and also changes authenc so that authsize is no longer a parameter of its template. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] api: Add aead crypto type This patch adds crypto_aead which is the interface for AEAD (Authenticated Encryption with Associated Data) algorithms. AEAD algorithms perform authentication and encryption in one step. Traditionally users (such as IPsec) would use two different crypto algorithms to perform these. With AEAD this comes down to one algorithm and one operation. Of course if traditional algorithms were used we'd still be doing two operations underneath. However, real AEAD algorithms may allow the underlying operations to be optimised as well. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: user - fix info leaks in report API Three errors resulting in kernel memory disclosure: 1/ The structures used for the netlink based crypto algorithm report API are located on the stack. As snprintf() does not fill the remainder of the buffer with null bytes, those stack bytes will be disclosed to users of the API. Switch to strncpy() to fix this. 2/ crypto_report_one() does not initialize all field of struct crypto_user_alg. Fix this to fix the heap info leak. 3/ For the module name we should copy only as many bytes as module_name() returns -- not as much as the destination buffer could hold. But the current code does not and therefore copies random data from behind the end of the module name, as the module name is always shorter than CRYPTO_MAX_ALG_NAME. Also switch to use strncpy() to copy the algorithm's name and driver_name. They are strings, after all.

crypto: aead - Convert top level interface to new style This patch converts the top-level aead interface to the new style. All user-level AEAD interface code have been moved into crypto/aead.h. The allocation/free functions have switched over to the new way of allocating tfms. This patch also removes the double indrection on setkey so the indirection now exists only at the alg level. Apart from these there are no user-visible changes. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: seqiv - Add support for new AEAD interface This patch converts the seqiv IV generator to work with the new AEAD interface where IV generators are just normal AEAD algorithms. Full backwards compatibility is paramount at this point since no users have yet switched over to the new interface. Nor can they switch to the new interface until IV generation is fully supported by it. So this means we are adding two versions of seqiv alongside the existing one. The first one is the one that will be used when the underlying AEAD algorithm has switched over to the new AEAD interface. The second one handles the current case where the underlying AEAD algorithm still uses the old interface. Both versions export themselves through the new AEAD interface.

[CRYPTO] aead: Create default givcipher instances This patch makes crypto_alloc_aead always return algorithms that is capable of generating their own IVs through givencrypt and givdecrypt.

crypto: user - Fix lookup of algorithms with IV generator We lookup algorithms with crypto_alg_mod_lookup() when instantiating via crypto_add_alg(). However, algorithms that are wrapped by an IV genearator (e.g. aead or genicv type algorithms) need special care. The userspace process hangs until it gets a timeout when we use crypto_alg_mod_lookup() to lookup these algorithms. So export the lookup functions for these algorithms and use them in crypto_add_alg().

crypto: aead - Avoid infinite loop when nivaead fails selftest When an aead constructed through crypto_nivaead_default fails its selftest, we'll loop forever trying to construct new aead objects but failing because it already exists. The crux of the issue is that once an aead fails the selftest, we'll ignore it on the next run through crypto_aead_lookup and attempt to construct a new aead. We should instead return an error to the caller if we find an an that has failed the test. This bug hasn't manifested itself yet because we don't have any test vectors for the existing nivaead algorithms. They're tested through the underlying algorithms only.

crypto: aead - Fix corner case in crypto_lookup_aead When the user explicitly states that they don't care whether the algorithm has been tested (type = CRYPTO_ALG_TESTED and mask = 0), there is a corner case where we may erroneously return ENOENT. This patch fixes it by correcting the logic in the test. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: aead - Convert top level interface to new style This patch converts the top-level aead interface to the new style. All user-level AEAD interface code have been moved into crypto/aead.h. The allocation/free functions have switched over to the new way of allocating tfms. This patch also removes the double indrection on setkey so the indirection now exists only at the alg level. Apart from these there are no user-visible changes. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] api: Add aead crypto type This patch adds crypto_aead which is the interface for AEAD (Authenticated Encryption with Associated Data) algorithms. AEAD algorithms perform authentication and encryption in one step. Traditionally users (such as IPsec) would use two different crypto algorithms to perform these. With AEAD this comes down to one algorithm and one operation. Of course if traditional algorithms were used we'd still be doing two operations underneath. However, real AEAD algorithms may allow the underlying operations to be optimised as well. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
